Exhaled breath is a significant source of SARS-CoV-2 emission	2020-06-02		.txt	text/plain	2791	170	64	Here, 35 COVID-19 subjects were recruited; exhaled breath condensate (EBC), air samples and surface swabs were collected and analyzed for SARS-CoV-2 using reverse transcription-polymerase chain reaction (RT-PCR). COVID-19 patients were shown to exhale SARS-CoV-2 into the air at an estimated rate of 103-105 RNA copies/min; while toilet and floor surfaces represented two important SARS-CoV-2 reservoirs. Surface swabs from the cell phone and hands of one patient(ITA-YL1) tested negative for the virus, but the SARS-CoV-2 was present on the toilet pit surface in that patient's hotel room (Fig. 1C ). Although EBC samples from two patients (ITA-YW2 and UK-YJ1) were shown to 20 contain SARS-CoV-2, surface swabs from their cell phones, hands, and toilet surfaces were negative for the virus. . https://doi.org/10.1101/2020.05.31.20115154 doi: medRxiv preprint Out of 242 surface swab samples, 13 were positive for SARS-CoV-2 ( Fig. 3 and Table S4 ).	./cache/cord-298343-nvuc1j7t.txt	./txt/cord-298343-nvuc1j7t.txt
